Rotary coffee bag holder

Abstract

The invention relates to a rotary coffee bag holder, comprising a base and a center pillar disposed thereon, the center pillar being rotatably connected with a coffee bag holder, wherein the upper end of the coffee bag holder is provided with a first turntable and a lower end is provided with a second turntable, the top end of the center pillar is mounted with a connecting seat, the central pillar passes through the second turntable, the connecting seat is matched with the first turntable, and the top surface of the connecting seat is provided with a boss against the first turntable. The boss is in contact with the first turntable in a point, with a small contact area, so that the rotation is smoother, more flexible, and the noise is lower; the rotation function realizes that the bearing does not need to be disposed.

What is claimed is: 
     
       1. A rotary coffee bag holder comprising a base ( 1 ) and a center pillar ( 2 ) arranged thereon, the center pillar ( 2 ) being rotatably coupled to a coffee bag holder ( 3 ), wherein, an upper end of the coffee bag holder ( 3 ) is provided with a first turntable ( 31 ), a lower end is provided with a second turntable ( 32 ), a top end of the center pillar ( 2 ) is provided with a connecting seat ( 4 ), and the center pillar ( 2 ) passes through the second turntable ( 32 ), such that the connecting seat ( 4 ) is engaged with the first turntable ( 31 ), and a top surface of the connecting seat ( 4 ) is provided with a boss ( 41 ) against the first turntable ( 31 );
 wherein the connecting seat ( 4 ) has a cylindrical shape, and a top end thereof is rotatably connected to a seat cover ( 311 ) disposed at a middle portion of the first turntable ( 31 ); a bottom end is inserted and fixed to the top end of the center pillar ( 2 ); 
 wherein a side of the connecting seat ( 4 ) is provided with a limit step ( 42 ) against the top end of the central pillar ( 2 );
